This is pretty promising! Especially for so early. The controls feel really smooth, although the planet landing is a bit finicky, I always want to try landing on a planet just a little further away from it. I love the look and the wobbling of the delivery ufos.
I would recommend adding something to make moving from point A to point B more interesting.
Imagine this, you can press space to boost every little while, and then there are asteroids or some other obstacle that if you run into you lose some resources? This would add a balance between getting resources quickly and not losing what you already have. Well maybe do something a little more interesting than that, but something along those lines.
Also I would recommend something for helping players with time management, some way for the player to know how much time they have left on their deliveries. The player wouldn't really need to know about the times on all their deliveries, just the one with the lowest time remaining. Maybe a little warning alarm goes off too if you're running out of time?
That's all just what I think, don't follow what I say at the detriment of whatever else you have planned of course.
